1. The electric light wire should not be too long, and the lamp head should not be less than 2 meters from the ground. The lamp cap should be fixed in one place. Do not pull it to avoid damage to the wires and the lamp cap, resulting in electric shock. 2. Do not touch the lamp, switch and socket with wet hands. When replacing the lamp, first turn off the switch and then stand on the dry insulation to change the lamp. If the switch, socket or electrical appliance is damaged or the casing is damaged, it should be repaired or replaced in time. It can not be used without repair. 3. The wires in the factory building can not be used to pull wires and mess with electrical equipment. It is forbidden to use multiple ports and old wires to prevent electric shock. Do not use the "one line, one ground" way to connect electricity. 4. When electrical equipment such as electrical equipment and electric lights need to be installed, it must be installed by an electrician. In the event of failure of the electrical equipment, it must be repaired by an electrician. 5. Electrical and mechanical equipment with mechanical transmission, must be equipped with protective cover, protective cover or protective fence for protection. It is not allowed to put the hand or body into the mechanical transmission position of the running equipment. When cleaning the equipment, it must be cut off. The power supply, the mechanical stoppage and the safety can be carried out to prevent personal injury or death. 6. Find the wires that fall to the ground, leave 10 meters away, and don't pick them up by hand. At the same time, try to look after the floor wire and ask the electrician to handle it in case someone approaches the electric shock. 7. When moving electrical equipment, be sure to pull the power off first, then move the equipment, never move with power. After moving the electrical equipment of the electrical equipment casing with a metal casing to a new location, first install the grounding wire and check the equipment to confirm that the equipment has no problem before starting to use. 8. When installing electrical equipment, it should meet the installation requirements. Do not use cracked or broken switches, lamp caps and broken wires. The wire connectors should be secure and wrapped in insulating tape. When it is found that there is damage, it is necessary to find an electrician to repair it in time. 9. Do not place flammable materials such as oil, cotton, wood chips, etc. near the lamp switch, fuse box and wires to prevent electrical fires. If you find the smell of burnt rubber and plastic, you should immediately turn off the power and shut down the power to find out the cause, and then close it. If there is a fire, you should quickly pull the fire to stop the fire. If you can't power off, apply the cover soil and cover the sand. Way to save the fire. Do not use water to save fire to prevent electric shock. 10. In the case of thunderstorms, do not approach the grounding wire of the high-voltage pole, tower, lightning rod and the grounding body to avoid electric shock due to the step voltage. 11. Power outages must be completed before the operation, power failure, power inspection, hanging grounding wire and hanging signage, set up temporary barriers and other security measures. 12. After a person is exposed to electricity, there are three ways to get rid of the low-voltage power supply: (1) power off the brake; (2) cut off the power cord; (3) disconnect the power supply from the insulation. 13. Never replace the fuse with copper wire, aluminum wire or iron wire. Replace the air switch immediately after it is damaged. The size of the fuse and air switch must match the power capacity. Otherwise, it may cause electric shock or electrical fire. 14. The metal casing of the electrical equipment must be reliably connected with the protection wire. The single-phase power should be connected by the three-core cable, and the three-phase power should be connected with the four-core cable to protect the neutral or grounding of the outdoor and low-voltage power grid. The device is reliably connected. The protective neutral must be grounded repeatedly. 15. The cable or wire must be wrapped with electrical tape, not replaced by medical tape, or wrapped with nylon paper. Do not use wires directly into the socket to use electricity. 16. When the appliance is found to emit smoke, emit a burnt smell or catch fire, it should be cut off immediately. Do not use water or foam fire extinguisher to extinguish the fire. 17. Electric furnaces such as electric furnaces and electric irons should not be placed directly on the wooden boards or close to flammable materials. If the electric heating equipment without automatic control is used, the power should be turned off to avoid fire. 18. Mobile electric appliances in the factory, such as floor-mounted fans, hand-held grinders, hand drills and other power tools must be installed with a leakage protection switch for single-machine protection. 19. If someone is found to have an electric shock, cut off the power supply or use a dry wooden stick or bamboo pole to pick up the wires, so that the electric shocker can be disconnected from the power supply immediately. If the electric shock is in a coma and the breathing stops, artificial respiration should be taken immediately and sent to the hospital for rescue. 20. The installation and maintenance of electrical equipment shall be performed by a licensed electrician. 21. When testing the 220V/380V three-phase four-wire power supply line with an electric pen, the wire to be tested that is brightened by the bubble is the live wire, and the zero wire is not bright. 22. When using your hand to measure the temperature of your electrical equipment, use your fingers instead of your palm. 25. In low-voltage work, the distance between the human body and the tools carried and the charged body is not less than 0.1m. 26. If the electric shocker stops breathing and the heartbeat remains, artificial respiration should be performed. 27. If the electric shock of the electric shock is stopped, the breathing is still there, and the extra-thoracic cardiac backlog should be implemented.
